关于vue.js:vue项目拖动实现修改左右宽度

需要：拖动实现扭转左右宽度
实现成果：

实现步骤：
1.代码

 <div class="box" ref="box">    <div class='left'>左侧</div>    <div class="resize" title="膨胀侧边栏">        ⋮    </div>    <div class='right'>右侧</div></div>

2.款式

.left {    width: 49.2%;    height:100%;    overflow-y:auto;    overflow-x:hidden;    float: left;}.resize {    cursor: col-resize;    float: left;    position: relative;    top: 45%;    background-color: #d6d6d6;    border-radius: 5px;    width: 0.6%;    height: 50px;    line-height: 50px;    text-align: center;    background-size: cover;    background-position: center;    font-size: 0.32rem;    color: white;}/*拖拽区鼠标悬停款式*/.resize:hover {    color: #444444;}.right {    height:7.8rem;    float: left;    width:50%;}.box {    width: 100%;    height: 7.8rem;}

3.办法

dragControllerDiv: function () {    var resize = document.getElementsByClassName('resize');    var left = document.getElementsByClassName('left');    var mid = document.getElementsByClassName('right');    var box = document.getElementsByClassName('box');    for (let i = 0; i < resize.length; i++) {        // 鼠标按下事件        resize[i].onmousedown = function (e) {            //色彩扭转揭示            resize[i].style.background = '#818181';            var startX = e.clientX;            // 鼠标拖动事件            document.onmousemove = function (e) {                resize[i].left = startX;                var endX = e.clientX;                var moveLen = resize[i].left + (endX - startX); // （endx-startx）=挪动的间隔。resize[i].left+挪动的间隔=右边区域最初的宽度                var maxT = box[i].clientWidth - resize[i].offsetWidth; // 容器宽度 - 右边区域的宽度 = 左边区域的宽度                if (moveLen < 32) moveLen = 32; // 右边区域的最小宽度为32px                if (moveLen > maxT - 150) moveLen = maxT - 150; //左边区域最小宽度为150px                resize[i].style.left = moveLen; // 设置左侧区域的宽度                for (let j = 0; j < left.length; j++) {                    left[j].style.width = (moveLen/document.body.clientWidth)*100 + '%';                    mid[j].style.width = ((box[i].clientWidth - moveLen)/document.body.clientWidth - 0.008)*100 + '%';                }            };            // 鼠标松开事件            document.onmouseup = function (evt) {                //色彩复原                resize[i].style.background = '#d6d6d6';                document.onmousemove = null;                document.onmouseup = null;                resize[i].releaseCapture && resize[i].releaseCapture(); //当你不在须要持续取得鼠标音讯就要应该调用ReleaseCapture()开释掉            };            resize[i].setCapture && resize[i].setCapture(); //该函数在属于以后线程的指定窗口里设置鼠标捕捉            return false;        };    }},

4.实现

mounted: function () {    let me=this;    me.dragControllerDiv();}
